OpenAPITools SDK

Introduction

OpenAPITools Python package enables developers to manage, and execute tools across multiple AI API providers. It provides a unified interface for working with tools in Anthropic's Claude, OpenAI's GPT models, and LangChain frameworks.

With OpenAPITools, you can:

• Create tools as Python or Bash scripts with standardized input/output
• Access these tools through a single, consistent SDK
• Integrate tools with Claude, GPT, and LangChain models
• Build interactive chatbots that can use tools to solve complex tasks

Installation

Prerequisites

• Python 3.8 or later
• Access keys to at least one of the supported AI providers (Anthropic, OpenAI, or LangChain)
• Get an API key for OpenAPITools from the Settings page

Install from PyPI

pip install reacter-openapitools requests

If you're using the LangChain adapter, you’ll also need to install `langchain` and `langchain-core`:

pip install langchain langchain-core

Tool Execution Details

Python Tools

• Python tools are executed using Python's `exec()` function directly in the current process
• Benefits:
  • No interpreter startup overhead
  • Full privacy (code runs locally)
  • Faster execution compared to subprocess methods
• Python tools receive arguments via an `input_json` dictionary and can access environment variables through `input_json["openv"]`

Bash Tools

• Bash tools are executed as subprocesses
• Arguments are passed as JSON to the script's standard input
• Recommended for non-Python environments for better performance
• Note: Bash tools should be tested in Linux environments or WSL, as they may not function correctly in Windows

Usage Modes

Local Mode (preferred)

adapter = ToolsAdapter(folder_path="/path/to/tools")

API Mode (rate limits apply)

adapter = ToolsAdapter(api_key="your_api_key")

Performance Considerations

• Python Tools: Best for Python environments, executed in-process with minimal overhead
• Bash Tools: Better for non-Python servers or when isolation is needed
• For maximum performance in non-Python environments, prefer Bash tools

Security and Privacy

• All tool execution happens locally within your environment
• No code is sent to external servers for execution
• Environment variables can be securely passed to tools

Integration with AI Models

OpenAPITools provides native integration with:

• Anthropic's Claude
• OpenAI's GPT models
• LangChain frameworks

This allows you to build AI assistants that can leverage tools to perform complex tasks.
